Stretching from the Simpson Bay area towards the Lowlands and Marigot, one finds the Simpson Bay Lagoon. Next to a recreation, this area has a mangrove forest area near Mullet Bay Beach.
Simpson Bay Lagoon is in the Pelican taxi zone. See the overview of St. Maarten taxi rates to check what pricing applies from your place of departure.
Buses make a practical alternative to taxis. The lagoon is situated on the Philipsburg–Maho line, with regular service.
